Genes affected

ARMC5 (HGNC:25781): (armadillo repeat containing 5) This gene encodes a member of the ARM (armadillo/beta-catenin-like repeat) superfamily. The ARM repeat is a tandemly repeated sequence motif with approximately 40 amino acid long. This repeat is implicated in mediating protein-protein interactions. The encoded protein contains seven ARM repeats. Mutations in this gene are associated with primary bilateral macronodular adrenal hyperplasia, which is also known as ACTH-independent macronodular adrenal hyperplasia 2. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.17990229).

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000793 (115/1450182) while in subpopulation NFE AF = 0.000099 (110/1111290). AF 95% confidence interval is 0.0000839. There are 0 homozygotes in GnomAdExome4. There are 53 alleles in the male GnomAdExome4 subpopulation. Median coverage is 35. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 7 AD gene.

Collection Method:clinical testing

The c.65C>T (p.A22V) alteration is located in exon 1 (coding exon 1) of the ARMC5 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the alanine (A) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
